Your opinion is worth something. Not much, but something. Companies are willing to pay for consumer feedback, and in this area, Google is no exception. It is happy to reward people for answering a few mundane questions. And now that offer extends out to people in Denmark, Norway, and Sweden.

I should stress, this is digital money. It's not the kind of useless currency you waste money on in games, but it's not real either. The only entity that accepts the form of payment Google offers is, well, Google. Getting digital currency to spend in the Play Store is a bit like living in a company town.

Nonetheless, Google's fake money buys you real apps, ebooks, music, or whatever else you want to spend Play Store credit on. Though when you're making up to $1 off each survey, you're more likely to buy apps, or app, than a music album. But hey, that's money that didn't have to come out of your bank account, credit card, PayPal, or some other source of digital currency considered more valuable.
